“Why do you think professional athletes practice all the time? So when it’s game time they know what they are doing and how to do it,” said Palm Beach Sheriff Ric Bradshaw. “So God forbid, if it’s game time, we know what to do.”

Operation Guardian will also test the region’s forensics teams (CSI) and Explosive Ordinance Disposal (EOD, or bomb squad) technicians, having them participate in additional scenarios at the port.

Operation Guardian furthers the ability of the RDSTF regional teams to implement training programs and improve all-hazards response capabilities to prevent, protect, respond and recover from such events.
